Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Round-leaved Feather-moss faces severe decline due to habitat degradation from agricultural intensification and urban development across its limited European range. Water pollution and eutrophication from agricultural runoff particularly threaten the clean, nutrient-poor aquatic environments this species requires. Climate change compounds these pressures by altering precipitation patterns and water chemistry in the specialized wetland habitats where remaining populations persist.

Threat summary

Habitat

This aquatic moss species inhabits clean, slow-flowing streams, springs, and seepage areas in calcareous regions, typically growing on rocks and stones in shallow, nutrient-poor waters. It requires stable water levels and high water quality, making it particularly sensitive to hydrological changes and pollution.

Frequently asked questions

Why is Round-leaved Feather-moss classified as Endangered?
Round-leaved Feather-moss is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Round-leaved Feather-moss faces severe decline due to habitat degradation from agricultural intensification and urban development across its limited European range. Water pollution and eutrophication from agricultural runoff particularly threaten the clean, nutrient-poor aquatic environments this species requires. Climate change compounds these pressures by altering precipitation patterns and water chemistry in the specialized wetland habitats where remaining populations persist.
Where does Round-leaved Feather-moss live?
Round-leaved Feather-moss occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Round-leaved Feather-moss?
The main threats to Round-leaved Feather-moss are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
